please use question 7 and 8 to answer question 9

7. Now let's find the Moon's centripetal acceleration and see how it compares to g. You will find the Moon's average orbital velocity. which you can use to calculate the average centripetal acceleration. The first step is to find the circumference of the orbit. The Moon orbits Earth at a radius of 3.85 x 10' m. What is the circumference of the Moon's orbit? Hint: You can use 'e" to put your answer in scienting notation. For example. the moon's orbital radius could be typed in as 3.85es to mean 3.85 x 10 2417810200 m Sulall Answer unlimited submissions remaining Score: Comments: 1/1 Great work! This is how far the Moon travels during one orbit. 8. The Moon takes 27.3 days. or 2.36 x 10's to make one orbit around Earth. What is the Moon's orbital velocity in mys? 1021.18644063 m/s Submit Answer unlimited submissions remaining Score: Comments: 1/1 Great work! We can use this as the Moon's velocity to find the centripetal acceleration. 9. Use your previous answers to find the centripetal acceleration of the Moon as it orbits Earth. m/s
